Abstract (en)

[origin: EP2719754A1] It is arranged to make it difficult to be affected by the difference between the specimens of the target cell and the difference in imaging conditions and so on. An image processing device 10 obtains a taken image obtained by imaging a sample including the target cell having a nucleus, then extracts pixels to be candidate of the nucleus from pixels included in the taken image based on a first condition determined in advance with respect to at least one of a color and a luminance, which the pixels to be the candidate are required to have, then further extracts a connected pixel group to be a candidate of the target cell from connected pixel groups, each of which is obtained by connecting adjacent ones of the pixels extracted, based on a second condition determined in advance with respect to a size and a shape which the connected pixel group to be the candidate is required to have, then sets a rectangular area, which has a predetermined size centered on the pixel included in the connected pixel group extracted, to the taken image, and then determines whether or not the target cell is included in the rectangular area based on whether or not an image feature amount obtained from the rectangular area thus set satisfies a condition of the image feature amount mechanically learned based on sample images of a positive example and a negative example of the target cell.
